You can use this package in your project by adding the following
to your Cargo.toml
:
[dependencies]
unicode-normalization = "0.1.19"
Modules§
- Methods for composing and decomposing characters.
Structs§
- External iterator for a string decomposition’s characters.
- External iterator for a string recomposition’s characters.
- External iterator for replacements for a string’s characters.
- UAX15-D4: This iterator keeps track of how many non-starters there have been since the last starter in NFKD and will emit a Combining Grapheme Joiner (U+034F) if the count exceeds 30.
Enums§
- The QuickCheck algorithm can quickly determine if a text is or isn’t normalized without any allocations in many cases, but it has to be able to return
Maybe
when a full decomposition and recomposition is necessary.
Constants§
Traits§
- Methods for iterating over strings while applying Unicode normalizations as described in Unicode Standard Annex #15.
Functions§
- Authoritatively check if a string is in NFC.
- Quickly check if a string is in NFC, potentially returning
IsNormalized::Maybe
if further checks are necessary. In this case a check likes.chars().nfc().eq(s.chars())
should suffice. - Authoritatively check if a string is Stream-Safe NFC.
- Quickly check if a string is Stream-Safe NFC.
- Authoritatively check if a string is in NFD.
- Quickly check if a string is in NFD.
- Authoritatively check if a string is Stream-Safe NFD.
- Quickly check if a string is Stream-Safe NFD.
- Authoritatively check if a string is in NFKC.
- Quickly check if a string is in NFKC.
- Authoritatively check if a string is in NFKD.
- Quickly check if a string is in NFKD.
